    An itemset is frequent if its support is no less than “minimum support threshold”. Minimum support is always supposed according to the choice. You can select any minimum support to decide that the itemset is frequent or not. What is support or absolute support?

Association rule learning - Wikipedia

    Association rule learning is a rule-based machine learning method for discovering interesting relations between variables in large databases. It is intended to identify strong rules discovered in databases using some measures of interestingness.

    – If an itemset is frequent, then all of its subsets must also be frequent • Aprioriprinciple holds due to the following property of the support measure: – Support of an itemset never exceeds the support of its subsets – This is known as the anti-monotone property of support ∀X,Y :( X ⊆Y) ⇒s(X) ≥s(Y) Data Mining: Association ...

    ing algorithms is to decouple the support and confidence requirements. From Equation 6.2, notice that the support of a rule X −→ Y depends only on the support of its corresponding itemset, X ∪ Y. For example, the following rules have identical support because they involve items from the same itemset, {Beer, Diapers, Milk}:

    Itemsets that meet a minimum support threshold are referred to as frequent itemsets. The rationale behind the use of support is that a retail organization is only interested in those itemsets that occur frequently. However, the support of an itemset tells only the …

Apriori Algorithm in Data Mining: Implementation With Examples

    https://www.softwaretestinghelp.com/apriori-algorithm/
    Nov 10, 2019 · This data mining technique follows the join and the prune steps iteratively until the most frequent itemset is achieved. A minimum support threshold is given in the problem or it is assumed by the user. #1) In the first iteration of the algorithm, each item is taken as a 1-itemsets candidate. The algorithm will count the occurrences of each item.
